Be it known that l, CARL E. AKnLnY, 'a citizen of the United' States, residing at New York, in the boroughs of Manhattan, city of New York, and State of 'New York, have invented certain new .and useful Improvements in Film-Boxes for Motion-Picture Camerasf of which the following is a specification- My invention relates to film boxes for motion picture cameras, adapted conveniently to hold a reel of film prior to'or subsequent to exposure, and is more Aparticularly designed yfor use in conjunction with that type of motion picture camera, disclosed, in Letters Patent No. 1,181,201, granted May 2, 1916, to Akeley'Camera, Inc., as my assignee.

M y improved film box is formed in two sections of substantially equal depth, one telescoping within the other, and adapted to be adjusted with respect to each other tof openand close the film aperture, and em-y bodies certain novel details of construction, both with respectto the rotation of the film spool and with respect to excluding light from the interior of the box when removed from the camera, as Ahereinai'."ter will be more definitely pointed out and claimed, reference being hadeto the accompanying drawings, in which Figure 1 is aside elevation of my improved box, the twosections thereof being vv' of rig. 2.

shown in closed position with respect to each other. l'

Fig. 2 is an edge view of the same. Fig. 3 is a "sectional view of the same taken on the line III-#III of Fig. 1.

Fig. 4 is a fragmentary view of the irte- "rior of one of thefs'ections showing the means for sealing the opening through which the rotating element of the box passes.

Fig. 5 is a sectional View, taken on the line Fig. 64 is a detail sectional viewof a portion of the telescoping rims of the two sections, showing said sections adjusted to position to permit the vfeed ofthe film therefrom y or thereto.:

Figxfy is a `top plan view of the film box shown in its closed position.

Similar numeralsof reference denote cor'- responding parts in the several views.

In the said drawings, the reference numeral 1 denotes one section of the film box provided with a'rim 2, and 3 denotes the other section of the box provided with a rim -l of substantially the saine depth as the rim 2.0i the section 1, said rim l being of a diameterhto telescope over the rim 2. The

rim 4e is recessedupon opposite sides at 5 to permit a grip on therirn 2 when the parts are in assembled position, whereby said 'section l audits rim 2 may be rotated with respect to the section 3 and rim Il. SaidI rim 4l is also provided with oppositely disposed angled slots 6, adapted to receive therein pins "y fixed to the rim 2, said pins, through their cooperation with said slots, forming a bayonet joint vconnection for locking the two sections in their assembled telescoped position.' Riveted tothe section l isa plate S formed with a spring arm which is apertured at its free end at l10 to engage over a. stud 11 fixed to the rim 4, said stud` being so positioned that this engagementA will taire place when the two sections are assembled and turned to their locked. position, and thereby will retain the parts in said position againstany but a positive displacement. The rim is slotted-transversely at 12,v said slot extending through the free edge of said rim, and the rirn 2 is correspondingly slotted at 13, said slots being so located as yto register with each other just vbefore the pins 7 reach the transverse portions of the slots 6, which latter is the position wherein the sections may be separated, but are completely out of register when the sections are adjusted to the position shown in Fig. 7 thereby excluding all light at this point under said adjustment. Fixed tothe inside of the rirn 2 adjacent the slot 13v is a spring plate 14 ha'ving a rolled edge 15 lying againstone' edge or" said slot, vas best seen in Fig. 5. This rolled edge 15 is so positioned that it will abut against one edge of the slot 12 of the' outer rim fr when the two sections are rotated almost to their unlocked position,

said rim are metal strengthening plates 16,

preferably vot' brass, said plates having upturned edgesy 17 adapted to enga' e inksuitable grooves fernuniN in the interior o the H6 vio till

lbeing removably camera to position the ihn box properly therein, said plates 16 also 'forming strength ening elements, of harder metal, the sections l and 3 and their rims preferably being formed oi? aluminum,

.The section 3 has riveted centrally to interior surface a circular plate l, from which projects centrally a shaft if), formed hollow for a. portion of its length. Similarly mounted centrally in the section l, as hereinafter described, is a stud ZO formed with aV projecting pin 21 adapted to engage the aperture in the shaft 19 when the two sections are assembled, whereby the parts 19 and 20 will be connected and centered with respect to each other. The stud Q0 is fixed toa nut '21@ slotted at toreceive a driving element in the camera and having its body portion slotted annularly at to receive a split metallic collar 24, the inner surface of said nut 2l beine; provided with spurs adapted, when the parts are assen'ibled, to penetrate and engage the wooden. hub 26 upon which the film is mounted, said hub disposed upon the shaft lil. Disposed between the split collar 2l and an inner metallicv collar 27 is a disk of leather or other flexible material 2S, which at its outer edge is iixed to the body l by means of a metal ring 29 suitably bolted to said tion l. This construction while it permits the free rotation of the nut Q1, which projects through an aperture 8O in the body i, at the same time eiiectually prevents ingress of anyilight whatever at this point.

in orieration, when the box is to be used as a feed box for illm, a spool 26 upon ivhich the lm is rolled is disposed upon the shaft 19, and the two sections of the box then brought together, the act of telescoping them causing the prongs 25 to penetrate 'the ends of the spool 26;" 1When the two sections'are telescoped so that the pins 7 register with. the longitudinal portions of the slots 6, the parts may be rotated with respect to each other until the transverse slot 13 in the rim 2 passes out oi register with the slot 12 in the rim el, this 'position being shown in Fig. 5, and the box then is sealed most ef fectually against access of light at any point, and is locked against any but a' positive displacement of parts by the engagement of the spring arm 9 on rim 2 with the stud 1G on .rim 4 The bor; then may be inserted into a came-ra, and the sections rotated toward the open position until the relative position shown in F'g. 6 is reached, which does not quite bring the pins 7 in' register with the transverse portions of the slots 6, but causes the slots i2 and 13 in the rims Z and et to register `with the rolled portion l5 of the spring 3.4 lying adjacent the edges of said slots on one side, and which acts as a guide for the hlm. With the parts in this non, the nos is ready tor feeding the lregister upon an adjustment or with respect to each other While in their ilnn which may be accomplished in any suitable manner, and may be accompanied by a rotation oi the nut '213, thereby rotating the film spool 2G. When the box is to be used as a receiver for exposed film, the two sections are separated and the film threaded through the aperture l2 and engaged with an empty spool 26 on the shaft l). rThe Section l is then telescoped into section 2, which causes the prongs 25 on nut El `to enter the spool 26, and said section l is then adjusted with respect to section 3 to the position of the rims 2 and 4, shown in Fig. G, which brings 'the rolled portion l5 of the spring le in proper position to act as a guide for the film in its: passage into the box. The nut 91 when the box 'is positioned properly in the camera, is engaged as to its slot 22 by a suitable projection on the operative parts oi the camera, whereby the said nut and conse ouently the spool Q6 are rotated to wind the tihn upon said spool as it is ted through the machine. YWhen the film is exhausted, the members ot the box are adjusted to the closed position shown in Fig. 5, when the box` and its contained film may be removed and carried to the dark room to fix the same.

,lV further and important function of the spring plate l-l and its rolled edge 15 is found in the fact that when the sect-ions are rotated to the'position shown in Fig. 5, said rolled edge l5 against the inner is Jforced face ot the rim 4, thereby forming a lightproof joint at that point, and efiectually preventing the admission of light.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent, isz-d `1. A 'film box, comprising two sections having rims of substantially equal depth.

adapted to telescope one 'within the other, said rims being slotted transversely and said slots adapted to be brought intoor ont of said sections telescoped position, and means for inciting said rims against separation but permitting relative rotation of said sectionsF 2. A film box, comprising two sections having rims of ,substantially equal depth adapted -to telescope one Within 'the other, said rims being slotted-transversely and said slots adapted to be brought into or ont o register upon an adjustment with respect to each other -While in their telescoped position, means for locking said rims against separation but permitting relative rotation of said' sections, and means for locking said rims against accidental relative rotation when the sections are adjusted to bring the transverse slots in the rims thereof out of register AWith each other.
